If the Bluetooth is installed, there is a box in the trunk (left side in the rack that would also hole the CD player and nav unit).

IIRC 2003 and later were prewired for Bluetooth, you had to add the hardware.

It works in a 2002 (most of the wiring is there, but you have to add the microphone). But not perfectly.

OK,I don't have Nav and the shark fin,so I'm not sure if the Bluetooth is installed.I bought this car new and never thought I had Bluetooth installed from the factory.I guess I'll have to go by my dealer and see if I can activate it.I'm pretty sure my car does not have it because in that left hand corner of the trunk all I have is the plastic on the floor of the trunk,unless it is behind the trunk liner in that left corner of the trunk.

My car is 05 that have blue tooth and it does not have that pair button Every time you start the car it automatic enter pairing mode for 30 seconds. Have your phone ready and search for it right after start the car

All E46 M3's have those two buttons on the steering wheel,at least in Canada they did.What would the passcode be,if the other post is correct in not needing the pairing button?Do you have the pairing button?

My 2002 E46 M3 has that button on the steering wheel. And officially, BT is not supported on the 2002 models.

IIRC, the code is on the ULF module. Looking for the pairing button was easier than pulling apart the trunk to see if the ULF is there. But if the car automatically goes into pairing mode, use your phone to see if it sees the car. THEN, you can go look for the pass code on the ULF.

The op did not mention if the car had navigation or not. For mine with nav the nav menu has a Telephone menu option on the main screen. I would thin this would show only if you had blue tooth. If so then I would do as suggested, enable bt on your phone, sit on the car and turn to position 2. You should see the car listed as available. If that works then go dig out the code. I has to do it on mine and its not that hard. Just remove the plastic fasteners carefully and you can get to it. There are several posts on google that show the exact location.

I will check it out tomorrow and see if it goes into pairing mode.How good is the Bluetooth on the E46?If it is really basic, I will probably just continue using my blue ant which works great?

I tried searching for devices on my iPhone Bluetooth today and nothing came up,so it looks like I don't have the system.Was that a dealer installed BMW Bluetooth system that you installed in your car and is the volume loud enough?
